Lorentz ECDRIVE 1800 C 1.7kW Solar Motor for Pump

Product Description

The Lorentz ECDRIVE 1800 C 1.7kW Solar Motor is a submersible direct current motor designed for professional solar pumping projects that require high performance and reliability in 4" wells. Its brushless technology, water filling, and AISI 304/316 stainless steel construction ensure robust, quiet, and virtually maintenance-free operation. With a maximum efficiency of 92% and IP68 protection, it converts more solar energy into useful flow, optimizing the investment in the photovoltaic field.

Main Features

• Nominal power of 1.7 kW, ideal for medium/high flow and head demands.
• Max efficiency 92% to obtain more water per watt of installed panel.
• Wide speed range: 900–3,300 rpm, adapts to variations in solar irradiation.
• Protection rating IP68 and water-filled motor for continuous submersible service.
• AISI 304/316 construction, resistant to corrosion and wear.
• No electronics in the motor: control and protections are managed externally.
• Compact format: Ø96 mm, height 203 mm, and weight 7 kg, suitable for 4" wells.

Advantages or Benefits

• Reduced total cost: high efficiency and brushless architecture minimize consumption and maintenance.
• High reliability: by dispensing with internal electronics, the motor is less sensitive to humidity and temperature.
• Stable operation: the rpm range allows for maintaining usable flow for more hours of the day.
• Long service life: stainless materials and IP68 sealing ensure durability in demanding environments.
• Simple integration into existing and new solar pumping systems.

Purpose or Applications

Recommended for 4" wells in residential or community water supply applications, drip and sprinkler irrigation, livestock, filling elevated tanks, filtration, and off-grid uses. In combination with centrifugal hydraulic bodies (C-SJ family), it offers high flow rates at medium heads, making it a versatile solution for farms, ranches, residential developments, and light industrial projects.

Technical Specifications

Compatibilities

This motor is compatible with Lorentz 4" centrifugal hydraulic bodies (C-SJ family) and with Lorentz solar pump controllers. It can be integrated into PS2 systems (the controller is supplied with the complete system) or mounted in PU units (the controller is not included and must be purchased separately). For correct selection, size the photovoltaic field according to the required flow and head, and verify that the controller supports the electrical range and working currents of the assembly.

With the Lorentz ECDRIVE 1800 C 1.7kW Solar Motor you will obtain a professional, efficient, and durable solution that maximizes hydraulic performance in 4" wells with minimal intervention and maximum reliability.
